Variable magnitude producing unit for training equipment, has coupling unit that includes slide arrangement, which depending on signals from central unit and three-phase motor is operable between two positions

摘要

The unit has two weight magazines coupled to toothed belts, where the magazines are fixed to a coupling unit (40).The belts are activated by a central unit (29).The coupling unit has a slide arrangement, which depending on signals from the central unit and three-phase motor (25) is operable between two positions, in which outgoing parts (18, 20) of belts run freely and brought into engagement with each other, respectively.
